Harmonic Spectrum & Otto Tuning Forks Set
The Harmonic Spectrum and Otto Tuning Forks Set is the ultimate professional toolkit for sound healers and somatic practitioners. This comprehensive 12-fork collection combines the full Harmonic Spectrum (8 forks) based on the Pythagorean Scale with the deep-vibrating Otto Tuners (32Hz, 64Hz, and 128Hz).
Whether you are working in the biofield to clear energy or applying weighted forks directly to the body for pain relief and grounding, this set provides all the frequencies needed for a complete therapeutic session.
These are the two sets required for The Sound Healing Academy’s Level 2 Diploma in Integral Sound Healing (for working with individual clients) and also for The Level 1 Foundation in Integral Sound Healing with Tuning Forks.
When bought together, these sets are discounted!
Please note that the Om Weighted Tuning Forks are also covered in both courses mentioned above. This fork is optional, and if you don't have this fork, you can use the Otto 128 Hz Tuning Fork instead.
However, there's one exercise where you can use both the Om and Otto 128 Hz together, so it's very useful to have both. If you wish to purchase the Om Weighted Tuning Fork as well, please add it to your cart.
The Harmonic Spectrum Unweighted Tuning Forks (Set Of 8 With Velveteen Case)
The Harmonic Spectrum 8-piece set contains a full octave of tuning forks (C, D, E, F, G, A, B, C).
They create a series of musical intervals to help you relax, centre yourself and release stuck, blocked energy.
Each interval can affect your nervous system in a different way by activating specific healing qualities. This is done by tapping two tuning forks together.
It's also possible to balance the energy in the chakras with this tuning fork set. This table shows the association between chakras and tuning forks:
| CHAKRA | TUNING FORK (NOTE & FREQUENCY) |
| Root Red | C 256 Hz |
| Sacral Orange | D 288 Hz |
| Solar Plexus Yellow | E 320 Hz |
| Heart Green | F 341.3 Hz |
| Throat Blue | G 384 Hz |
| 3rd Eye Indigo | A 426.7 Hz |
| Crown Violet | B 480 Hz |
| Higher Octave Of Root White | C 512 Hz |
The Otto (Ostheopathic) Weighted Tuning Forks (Set Of 3 With Cases)
Otto tuning forks are used for relaxation and for sending vibrations into the bones. The forks are tuned to 32 Hz, 64 Hz, and 128 Hz. They vibrate at a low pitch due to their weighted prongs and are especially effective when placed on the sternum, vertebra and meridian points. These frequencies project sounds into the physical body, especially in the bones.
The Otto 32 Hz Weighted Tuning fork
C-32 Hz is helpful for the following:
- Good for stimulating the flow of lymph
- Boosting the immune system
- Repairing and regenerating peripheral nerves
- Enabling greater mobility of cranial bones and helping to relieve migraines, headaches, and mood swings
- Stimulates hair growth
- Good for grounding
The Otto Tuner is the note of C in the diatonic scale.
The Otto 64 Hz Weighted Tuning Fork
C-64 Hz is helpful for the following:
- helps loosen sacral ligaments
- stimulates and balances between the sympathetic and parasympathetic nervous systems
- useful in healing emotional trauma
- grounding
The Otto 64 Hz is very effective when used around the sacrum, as it helps balance the autonomic nervous system.
It assists in the following:
- Better sleep
- Reduced aches and pains
- Lifting depression
- Overcoming sexual and menstrual dysfunctions
- Improved immune system
The Otto 128 Hz Weighted Tuning Fork
The Otto 128 Hz reduces pain in joints and can be used on or around stiff or painful joints, on the sacrum, and on Chakra points.
Benefits include:
- Increases joint mobility
- Spikes nitric oxide
- Stimulates endocrine glands
- Releases the psoas muscle
- Relaxes the organs within the pelvis
It's an excellent tuning fork to use alongside the Weighted Om, as the combination with the notes being so close creates a dissonance that assists in breaking up stuck energy.
These instruments are made from special grade aluminium alloy and their frequency is guaranteed to be tuned to an accuracy of +/- 0.25%.
All tuning forks come in a velveteen carry bag and they are made in India, they're cut (not moulded) and are of great quality and value.
